t MPRovi-:MENT 1N PIPE-couPUNe-s.

The Schedule referred to in these Letters Patent and making part of the name.

To all whomlit may concern Be it 'known that I, GEORGE C. GERMAIN, of Onyahoga Falls, in the county of Summit and State of Ohio, haveinvented a new and improved Mode of J ointing Sections of Pipe; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying' drawing forming a part of this specification.

' Thepurpose of my invention is to form a cheap and tight coupling-joint for pipes generally, but especially for ditching-pipes. These pipes are oi' iron, clay, or

' other suitable matelial, and are made in short sections,

which are usually coupled together by a sheet-metal sleeve, rendered `tight by water-lime. this object by means of a wrapping of canvas saturated in asphaltumor aualagous substance.

In accordance with the requirement of the' patent .law I will describe the method which I preferably employ in the application of my sleeve:

I soak asheet of canvas of suitable width in some liquid water-repellant and adhesive solution, and wind it therefrom on a mandrel. From this mandrel it is wound about the two sections of a pipe at their point of junction.

The pipes are placed in contact with the mandrel I accomplish for the purpose of condensing the adhesive and waterrepellant substance into the iii-bric.' Figure 1 is a longitudinal, and

Figure 2, a cross-section of two pipes joined together.

A and B are two sections of a ditching-pipe made of iron or clay, aud l O, the saturated canvas. The sections of pipe, akettle of adhesive repellent,

and the rolls of canvas are taken in wagons to the'- lhe pipes are then place where they are to be used. coupled on the spot and immediately applied to the ditch or drain.

Having thus described all that is necessary to a full understanding of 1n y invention,

What I claim as new, and-desire to protect by Let- 4ters Patent, is

The application of a canvas wrapping C, saturated in some adhesive water-repellant, to the sections A B of an iron or clay pipe, for the purpose of forming a tight joint, as described.
